Wait for “git clone” to finish in bash

luftwaffe · 05-25-2016, 07:27 AM

I have a sequential script in which there is a git clone. I would like to make sure that the actual git process is finished before executing the next step. I tried

Code:

git clone https://github.example.com/Sample/Example.git & export PID=${!} | while [[ ( -d /proc/$PID ) && ( -z `grep zombie /proc/$PID/status` ) ]]; do sleep 1; done

and various other ways but could not manage how to wait until the actual git clone is done. Any hint on this one please?

use double & instead of single one:
git clone ... && another command
but I still do not understand that | before while

There is a shell script what invokes "git clone" to replicate a source tree on which some operations are done. The problem is that git clone runs async spawning a number of "git-remote-https" jobs to download the repo content and then it returns immediately.
The question is how I can check when a particular git clone is fully completed when run by cron and know that the repo is complete while other git commands may run with the same name.
Is there any way to force git to be synchronous?

maybe:

Code:

git clone https://github.example.com/Sample/Example.git &
PID=$!
wait $PID

Which is of course identical to just

Code:

git clone https://github.example.com/Sample/Example.git

because git runs synchronously by default...
